摘要
生态评价对自然保护区的科学有效管理和可持续发展具有重要意义。本文基于空间分辨率为30 m的Landsat影像和时间分辨率为8 d的GLASS数据,采用由生态环境功能指数、生态环境稳定指数、生态环境胁迫指数加权构建的生态环境质量指数(EQI),对2005—2019年金花茶自然保护区的生态环境质量进行评价。结果表明,金花茶自然保护区生态环境质量整体良好;2005—2019年生态环境质量不断得到改善;生态环境质量等级为差和低的区域主要分布在保护区四周,所占比例自2014年逐年增加,这与周边居民人为活动密切相关。
Ecological evaluation is of great significance for the scientific and effective management and sustainable development of nature reserves.Based on Landsat images with a spatial resolution of 30 meters and GLASS data with a time resolution of 8 days,this paper uses ecological quality index(EQI),which is calculated as weighted ecological function index,ecological stability index,and ecological stress index,to evaluate the ecological environment quality of Fangcheng Golden Camellia National Nature Reserve in Guangxi from 2005 to 2019.The results show that the overall ecological quality of the reserve is good.The quality of the ecological environment is continuously improving during 2005—2019.Areas with poor and low ecological grades are mainly distributed around the protected area,and their proportion has increased year by year since 2014.This is closely related to the human disturbance activities of the surrounding residents.
